“Woman is the central point of the natural groups arising from sexual intercourse and reproduction; man, on the other hand, is the creator of free forms of society based upon the sympathy of like kinds.” The development of the individual personal marriage is most intimately dependent upon patriarchy. In this sense, but only in this sense, Eduard von Mayer is right when he points to man as the true creator of the family. For under the matriarchal system the “family” was incomplete: it consisted only of mother and child. Only with the development of patriarchy could the family become a complete whole.

The =rape of women= and =marriage by capture= belong to the beginnings of patriarchy; later, when woman, completely enslaved, had fallen to the position of a mere chattel, =marriage by purchase= was introduced. The debased position of women under the domination of the primitive father-right can be best studied among the Greeks, where free sexual relationships were possible only in connexion with hetairæ and the love of boys. To the Greeks of classical antiquity the love of boys was precisely that which to the modern civilized man hetero-sexual love is, resting upon the most personal, most individual, most spiritual contact and understanding. Kohler has beautifully described the bright side of the complete and unrestricted father-right:
